    That hard brass thing is the slow speed jet. It unscrews.

    Combustion Problem?

    Idle speed is set with the idle stop screw. But odds are the low speed circuit is still crudded up.

    Combustion Problem?

    Unfortunately the Factory service manual is now out of print. The decompressor is a weight on the camshaft. Clogged low speed circuit can be an issue. You would need to buy a leak down tester. And you need compressed air. Timing is seldom off. If the belt came loose or snapped, you would bend at...

    Yes, it does.

    Combustion Problem?

    Pumping and squirting shows the accelerator pump is working. It does not indicate there is a good low speed circuit. Only a proper soaking and then a blow out will clear that.

    05' Tohatsu 15 4 stroke. Starts and dies within seconds.

    Oil in the cylinder would cause a liquid lock, aqnd you would not be able to crank. I would verify good spark and clean the carb properly.

    2013 30hp Tohatsu/Nissan EFI wont start weird problem

    So either the pump is shorted, or you can't deliver enough power. That's either bad wiring (corrosion) or a bad ECU.

    05' Tohatsu 15 4 stroke. Starts and dies within seconds.

    Yes, if the motor is laid down on the wrong side.

    Tried everything, except what's really wrong.

    You need to properly clean the carb. Just spraying acetone type generic cleaner is not adequate.

    05' Tohatsu 15 4 stroke. Starts and dies within seconds.

    You really should start a new thread. But yes, over full oil can be an issue. And if you end up with the tiller up, yes, you can get a liquid locked cylinder.

    Over full oil will foam and cause extreme crankcase pressures.

    Tried everything, except what's really wrong.

    Did this just happen, or have there been issues for a while? You replaced the alternator? Never saw one fail. What is the voltage out of the alternator going into the CD? Did you test the CD? What method did you use to clean the carburetor? Do you now have spark?

    05' Tohatsu 15 4 stroke. Starts and dies within seconds.

    It died of extreme crankcase pressures and foamed up oil.

    What is your WOT RPM? Is the oil even a drop over full? Have you checked for a spun prop? Check all that first.

    05' Tohatsu 15 4 stroke. Starts and dies within seconds.

    Good idea to change the filter as well.

    The ABS solenoid is an expanding wax capsule with a heater in it. If you apply 12v to it, you should see the needle slowly lengthen. As long as it's seated, all should be good. The carb must be impeccably clean. Also verify oil level below the full mark.
